The Lowdown
Alright, folks, Rusty here. Let’s have a look at what’s cookin’ for Kennebunk Beach over the next couple of weeks. I gotta be straight with you—it’s gonna be a long, quiet stretch.
We’re looking at a real flat spell kicking things off. The water temp is sittin’ at 65°, which is a touch warmer than normal for this time of year, so at least the paddle out won’t be a shock to the system. But for the first week and a half, there’s just nothin’ doin’. The combined wave energy is weak, barely cracking double digits, and the swell heights are tiny—mostly under 2 ft. You’ll see a few days with a bit of a bump, like the afternoon of the 13th with a 5 ft swell from the S, but that’s comin’ with a short period of 5 seconds and onshore wind, so it’s gonna be a messy, crumbly mess. Not worth gettin’ wet for.
There’s a real gap here. From now until the 20th of September, it’s mostly just knee-high dribble and choppy conditions. The wind’s all over the place—cross-on, cross-off, onshore—and nothin’ aligns to give us a clean wave.
Now, if you’re patient, there’s a tiny glimmer. On Sunday the 20th, we get a bit of a pulse. The afternoon shows a 4 ft swell from the NE, with a period of 6 seconds. The combined energy jumps to 172 (moderate), and the wind is a clean cross-off from the NNW. That’s the best lookin’ window in the whole run. It’s not a standout by any stretch, but it’s the only time the conditions line up for a surfable wave. The break is sheltered from the NE, so that swell direction works in its favor.
Then, on Tuesday the 22nd, we get a little more size. The morning brings a 6 ft swell from the ESE, period of 6 seconds, and the combined energy is 218 (moderate). The wind is glassy—zero from the ESE. That’s clean. But by the afternoon, the swell jumps to 7 ft from the NE, with a 6-second period and energy at 731 (strong). That’s gettin’ into the expert-only zone, and the wind is a light cross-shore. It’ll be a bit unruly, but if you’re a seasoned local, that afternoon could offer some punchy, heavy closeouts.
The rest of the run after that? Fades back into the small stuff. Honestly, this is a lean period for Kennebunk Beach. The break is fairly consistent, but the conditions just aren’t there. If you’re itchin’ for a paddle, the 20th afternoon or the 22nd morning are your best bets. Keep an eye on the wind, because when it’s glassy, even a small wave is worth a session.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Kennebunk Beach is 17 km (11 miles) from Biddeford. If you plan a vacation in Maine, look for hotels and other accommodation in Biddeford. Biddeford has rooms for a wide range of budgets as well as car hire and transport links.
